The only "lock" code points I could find are U+1F512 closed lock and U+1F513 open lock.  These are in the "Miscellaneous Symbols and Pictographs" area, U+1F300 - U+1F5FF.  I don't know that there are flavors elsewhere (e.g., under Emoticons).  I do see different renders of "unlocked," some with the hasp shown rotated, but I don't see any other code points.

Assuming you don't want to go through a request to the Unicode Consortium for a new glyph and codepoint, the available places for private use are

U+1F300 - U + 1F5FF (with end-user usage recommended to start at the low end),
 
U+F0000 - FFFFD, and 

U+100000 - U+10FFFD.  

Use in interchange depends on agreement among the parties, and that's all outside of the Unicode standardization provisions.

Is this even close to what is being asked for?
